Abstract

A system provides for automated control of solvent evaporation, such as may be done for solvent exchange in a solvent that contains analytes or extractants. The automated control is able to ascertain and take appropriate action when a solvent is boiling, when the extractants are free or dry of the solvent, and when there is thermal cycling of the solvent.
